Documentation/UserGuide/Non-ideal MHD

A variety of non-ideal MHD effects can be added, including Ohmic resistivity, the Hall effect, and ambipolar diffusion. In all cases, configure the code with

% configure --enable-resistivity

Each effect is added at first-order via operator splitting.

The update is explicit in time, so that a very restrictive CFL constraint on the time step will be used.
